Niomi Arleen McLean-DaleyMBE (born 26 April 1981), better known as Ms. Dynamite, is an English rapper, singer, songwriter and record producer. She is the recipient of the Mercury Music Prize, two Brit Awards and three MOBO Awards.

Ms. Dynamite (originally Lady Dynamite) was first known for her vocals on the UK garage underground track "Booo!", which was regularly played on London pirate radio stations and was later released as a single. While working at the radio station RAW FM, Ms. Dynamite was discovered by Richard Forbes ("DJ Sticky") at a West Endclub. Interest grew from all major British labels and eventually she was signed via her management Bigga Beats to Polydor Records, where she met producer Salaam Remi, who cultivated her talent.

On 11 September 2005, she returned to the limelight (having taken time off to have her son, Shavaar) with a new album titled Judgement Days. Featuring more social commentary, in songs such as the first double A-side single, "Judgement Day"/"Father" and the Tony Blair critique, "Mr Prime Minister," reviews of the album were not as favourable as those of her debut. However, "Judgement Day" reached No. 25 in the UK Singles Chart.[3]

After taking a break from the music scene, Dynamite guest-hosted BBC Radio 1Xtra, and stated she would be releasing a third album, Democracy, in 2009, with the first single from the new album being "Bad Gyal".[4] However, this was later pushed back as she concentrated on other projects and motherhood. Meanwhile, she appeared on Hell's Kitchen on ITV1 in 2009,[5] finishing fourth, and later as an expert adviser on Goldie's Band: By Royal Appointment on BBC Two.[6]

Since then she has appeared on several collaborations, notably Katy B's second single, "Lights On", which peaked at number 4 in the UK singles chart in 2010, and the Magnetic Man track "Fire", which appeared on their debut album.
